A decade after their children vanished, the parents of 43 Mexican students, presumed to have been massacred, hope that a new president will finally reveal the truth about the tragedy. Relatives of the missing students demand answers from the incoming president. "If a man didn’t do it, let a woman do it," says Maria de Jesus Tlatempa, mother of Jose Eduardo Bartolo Tlatempa, one of the 43 students who disappeared in 2014. As the 10th anniversary of their disappearance approaches, the families continue to fight and hope to one day find them. IMAGES AND SOUNDBITES
